CASH INDICATOR AND REGISTER.

SPECIFICATION forming part of Letters Patent No. 414,872, dated November12, 1889.

- Application filed April 20, 1889. Serial No. 308,041. (No model.)

To all whom, it may concern:

Be it known that I, JOHN SHARPE, a resident of Toronto, in the Provinceof Ontario and Dominion of Canada, have invented certain new and usefulImprovements in Cash- Registers; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it pertains to make anduse the same.

My inventionrelates to an improvement in cash-registers; and it consistsin the peculiar construction and combination of devices hereinafterdescribed and claimed.

I 5 The object of my invention is to provide a cash-register which isadapted to register the amount of each sale and to keep a correctaccount of the sum total of all the sales for any desired length oftime, and which is provided with safeguards to prevent it fromregistering inaccurate sums and to prevent it from being tampered withby dishonest persons to cause the machine to falsify the accounts.

Afurther object of my invention is to provide a cash-register whichis.adapted to be caused to register several amounts at the same instant.I

I A further object of my invention is o provide a cash-register which ispositive and automatic in operation, is necessarily accurate, is strongand durable, and is not likely to get out of order.

These objects I attain by the mechanism hereinafter described, andillustrated in the accompanying drawings, in which Figure 1 is a frontelevation of a cash-register embodying my improvements, parts of thecase being removed to disclose the interior mechanism. Fig. 2 is avertical transverse sectional view of my improved cashregister. Fig. 3is a horizontal sectional view of my improved cash-register, taken on aplane above the upper ends of the verticallymovable ratchet-bars, thefront part of the case being removed to disclose the operatingmechanism, and parts engaging the disks Y H being omitted for the-sakeof olearness.

Fig. 2-0 isa detailed perspective view of the detent to lock the tumblerrods. Fig.21 is a partial elevation of one end of the interior frame supportingthe mechanism. Fig. 22 is a detailed elevation of the I wrench employedto set the registering-disks.

The bottom of the cabinet or case A is slightly inclined toward thefront side of the case, and on the upper side of the bottom are mountedanti-friction rollers B, which support the-cash-drawer C. An opening I)is made in the front side of the casein front of the drawer, and throughwhich the latter is go adapted to slide when opened, and the saidopening is covered by a shield-plate E, which is hinged at its loweredge, as at F. At the ends of the shield, and at right angles thereto,are quadrant-plates G, which extend 5 into the case on opposite sides ofthe drawer and are provided at their lower inner corners with projectingshoulders H. Pins I project from the outer sides of the quadrant-plates,and are located about the centers of the quadrant-plates and near theircurved edges, as shown. A pair of flat springs K are secured to across-bar L under the bottom of the case, and the free ends of the saidsprings bear up under the shoulders H and serve to throw theshield-plateE open and disclose the front end of the drawers when theshieldplate is released by the mechanism now to be described.

A pair of hooks M are mounted in the ends of the case on pivots N, andare arranged on opposite sides of the drawer. The shoulders O at theouter ends of the said hooks engage the pins I, and thereby normallyretain the shield-plate in a closed position against the pressure of thesprings K, and the inner ends of the said hooks are provided withelongated slots P. A pair of vertically-movable rods R is guided inopenings in guide-brackets S,

which are arranged in pairs and attached to the ends of the case abovethe drawer and one above the other, as shown. The upper ends of the rodsR are bent outward at right angles to form tappets T, and the lower endsofthe said rods are attached to the inner ends of the hooks by pins U,which work in the slots P. On the rods R are arranged coiled extensilesprings V, which bear between the upper brackets and pins W on the rodsand serve to normally force the latter down, and thereby retain theshoulders of the hooks in contact with the pins I. A pair of weight-armsX are arranged at the ends of the case and pivoted at their outer ends-on pins Y. The lower inner corners of the said weight-arms areconnected together by a rod Z, which extends lengthwise across the case,and hence causes the weight-arms to operate in unison. On the outersides of the weight-arms are arranged right-angled tappet-arms A, whichhave slots B in their vertical portions. Set-screws O extend throughthese slots and enter threaded openings in the weight-arms and serve tosecure the tappet-arms thereto and adapt the latter to be adjusted. Thehorizontal, portions of the arms A extend into the paths of the tappetsT on the upper ends of rods R,and are adapted to engage the same whenthe weight-arms are raised by any of the keys, and thereby cause thesaid rods R to disengage the hooks 0 from the pins 1, and thereupon thesprings K open the shield-plate E. The opening D being thus uncovered,the drawer slides open by gravity, as will be readily understood.

On the sides of the drawer, at a suitable distance from the front sidethereof, are secured vertical plates D, and from the inner sides of thequadrant-plates G, near the lower corners thereof, project pins E,which, when the shield-plate is thrown open. by the springs, engage therear sides of the plates D, and thereby impart the initial impulse tothe drawer and start the same on its outward movement.

When closing the drawer, which may be done by pushing on the handle F onthe front side thereof, the plates D engage the pins E, and as thedrawer is moved inward the said pins travel down on the rear edges ofthe plates and serve to turn the shield-plate on its hinges against thepressure of the spring K and close the shield-plate over the opening D,when the hooks M engage again the pins I and lock the shield-plate inits closed position, and thus render it impossible to open the drawerwithout previously operating one of the keys.

Arranged in the case near the ends thereof, and rigidly secured in placein any suitable manner, are a pair of standard-plates F which supportall of the interior mechanism. The main shaft G of the registeringn1eohanism is j ournaled in bearings in the said standard-plates andextends entirely across the case near the front side thereof. At one endof the main shaft is formed an angular extension H, adapted to beengaged by a suitable wrench or key Isuch as illustrated in Fig. 22-andthereby the main shaft is adapted to be revolved in its bearings for thepurpose of turning all the numbered disks to the zero or naught point,as will be presently described.

Arranged on the main shaft, and loosely and independently revolublethereon, is a series of disks 1 2 3 4c 5 6, each of which. is providedon its periphery with a series of numerals from 0 to 9, arranged atsuitable regular distances apart. The numerals on disk 1 indicate cents,those on disk2 indicate dimes, those on disk 3 indicate dollars, thoseon disk 4 indicate tens of dollars, thoseon disk 5 indicate hundreds ofdollars, and those on disk 6 indicate thousands of dollars. Of coursethe number of disks may be increased at will to adapt the machine forregistering sums of any desired magnitude. The said disks are providedwith spur-wheels 1 2 3 t 5 6, respectively, the said spur-wheels beingrigidly secured to or formed integrally with their respective disks, asmay be preferred, and the said wheels being all of the same diameter andprovided with the same number of teeth.

The hub or central sleeve K of each disk carries a stop-pin L and aspring M to normally force the same inward. The inner ends of these pinsare beveled 011 one side, as shown in Fig. 18, and said inner ends ofthe pins travel in annular grooves N in themain shaft. Each groove N hasan oifset or shoulder 0, one side of which is inclined and the otherside of which is radial. The stop-pins are arranged in the hubs orcentral sleeves of the disks in line radially with the naughts orzero-marks on said disks, and hence it follows that when the straightsides of the inner ends of the stop-pins are in engagement with theradial sides of the shoulders or offsets 0 all of the disks will presenttheir naughts or zero-marks to the openings 'P of a coverplate R, whichplate is secured on the inclined front edges of the standard-plates. Ahinged cover S, with which the case is pro vided and which is usuallylocked, is ar- IIO I lip U of suitable length.

ranged over the plate R, and when the said cover S is opened theopenings P are disclosed and the numbers on the disks presented to saidopenings can be read. A sleeve 1 extends from one side of the wheel 1and is secured firmly thereto. The said sleeve is loose on the shaft G,and at the outer end of said sleeve is firmly secured a spur-wheel 1,which is exactly similar to its fellow wheel 1. A sha'ft T is arrangedparallel with the shaft G and at a suitable distance therefrom, and hasits ends rigidly secured to the standardplates. On this shaft T isloosely mounted a series of spur-wheels U V W X Y Z,

which are all of the same diameter and have the same number of teeth.The wheel U engages the wheel 1, the wheel V engages the wheel 2, thewheel WV engages the wheel 3, the wheel X engages the wheel 4., thewheel -Y engages the wheel 5, and the wheel Z engages the wheel 6.

The wheels X, Y ,and Z are each provided on one side with aseriesoftappet-pins A113 and 0 respectively, corresponding in number to thenumerals on the disksthat is to say, there are ten of the said pins oneach of the said wheels. Each disk 3 L 5 is provided with a radialtappet-pin 3 4L 5, respectively, which are in the paths of the pins onthe wheels X, Y, and Z, and are arranged between the numerals O and 1 ontheir respective disks. Pawls D engage the wheels X, Y, and Z, and serveto prevent the same from turning in a reverse direction from thatindicated by the arrow E? in Fig. 2.

A shaft F is arranged lengthwise between the standard-plates andparallel with and at a suitable distance in rear of and below the shaftT. On this shaft F is loosely mounted a sleeve G which has tenratchet-teeth, the width of which is equal to the length of the sleeve.Rigidly secured to the-said sleeve is a spur-wheel H which engages theloose similar spur-wheel V on the shaft T, the latter wheel en gagingthe wheel 2; hence when rotary motion is imparted to'the said sleeve thedisk 2-will be turned.

Arranged at a suitable distance above the shaft F and parallel therewithis a shaft K on which are loosely mounted a pair of ratchet-sleeves L Mwhich are similar to the ratchet-sleeve G The ratchet-sleeve L has aspur-wheel N that meshes with an idlewheel U on the shaft T, whichidle-wheel engages the wheel 1. The ratchet-sleeve H has a spur-Wheel Rthat meshes with an idlewheel W, also on shaft T, which idle-wheel WVmeshes with the wheel 3.

Loosely mounted on the shaft T is a rock ing detent T that has ahorizontal engaging- From one end of the detent projects an arm V Aspring W is attached to the shaft at a point about midway between theends of the rocking detent, and the free end of the spring bears againstthe rear side of the lip, and hence moves the same normally in onedirection. A pivoted dog X is normally held in engagement with the arm Vby a spring Y and at the inner end of the dog is an arm Z which is inthe path of a tappet-pin A that projects from the ratchet-sleeve L atone end thereof. A spring pressed pawl B engages the said ratchet-sleeveto prevent the same from rotating in a reverse direction.

On a suitable shaft (I is loosely mounted a rocking detent D which has ahorizontal engaging-lip E of suitable length, and from one end of thesaid detent depends an inclined arm F A spring G is attached to theshaft 0 and its free end bears against the rear side of the lip E andmoves the detent normally in one direction. A spring-pressed dog Hnormally engages and holds the arm F and the arm I of the dog is in thepath of a tappet-pin K that projects from the wheel H at one end of theratchet-sleeve G A spring pressed pawl L engages the said ratchet-sleeveand holds the same against reverse rotation.

A substantially semi-cylindrical ratchettumbler sleeve M is looselyjournaled on a shaft N and has a seriessay eight-of ratchetteeth 0 whichextend its entire length and are concentric with the shaft. That side ofthe tumbler which is provided with ratchet-teeth is necessarily heavierthan the other or cut-away side thereof, and therefore theratchet-tumbler is normally in the position shown. 011 the center of thecutaway portion of the ratchet-tumblerisasemicircular web or flange P,which is provided with ratchet-teeth R Arranged on the same shaft withthe tumbler M end to end, are a pair of similar ratchet-sleeve tumblersS T Gravity-pawls U engage the flange or web ratchet-teeth R of therespective tumblers. The function of the said tumblers will appearhereinafter.

On a suitable shaft V? are pivoted three banks of finger-keys 1 2 3,there beingnine keys in each bank, and the said keys of each bank beingnumbered, consecutively, from 1 to 9. Hubs or sleeves W are formed onthe arms of the keys, which bear against each other end to end and serveto space the said finger-keys to the necessary distance apart. Theinward-extending arms X of the fingerkeys pass under the rod Z, whichserves to connect the weight-arms, the said arms X extending to within ashort distance of the back Y of the case. The said back is secured inplace by screws or other suitable devices and is removable from thecase. Each finger-key is independent of all the others and forms a leverof the first class.

Three series of vertically-movable ratchetbars 1 2 3 are maintained inposition by guide-bars Y or other suitable devices. There are as many ofthe ratchetbars as pivoted at its lower end to the rear end of the arm Xof its respective fin ger-key by means of a pin Z which operates in aslightly-elongated slot A made transversely in the ratchetbar. The'ratchet bars are arranged and maintained at a slight distance in frontof the ratchet-tumbler sleeves, and each ratchet-bar has on its rearside a series of ratchet-teeth 13*, which correspond in number to andare adapted to engage the teeth M of the ratchettumblers when theratchet-bars are moved upward. The said ratchet-tumblers thus serve tokeep the teeth F" of the ratchetbars in engagement with theratchet-sleeves while the ratchet-bars are moving upward, andwhen theratchet-bars reach the upper limit of their stroke their teeth B will,meshing with the teeth M of the ratchet-tumblers, have turned the latterabout half a revolution, so that the heavier sides are uppermost, andthe impulse of the ratchet-bars causes the ratchet-tumblers to completetheir revolution. It will be understood that while the teeth M are outof engagement with the teeth B the ratchet-bars will be free to descendby their own gravity and the assistance of the weight-arms X, theirteeth slipping idly on the ratclietsleeves, thus restoring the bars,tumbler-sleeves, and fin ger-keys to theirinitial position. The upperguide-bar Y has on its front side a series of notches G which receivethe rear sides of the ratchet-bars and maintain the latter at therequired distance apart, and the inner sides of .said notches areinclined, as shown at D, Fig. 2. On the rear side of each ratchet-bar,near the upper end thereof, is an inclined offset cam E, which isadapted to engage the inclined side D of its respective guide-notch whenthe ratchet-bar reaches the lower limit of its movement, and therebymove the upper end of the ratchetbar forward and move its ratchet-teethF forward laterally into the path of its respective ratchet-sleeve.

The ratchet-teeth F of the ratchet-bars of each bank of finger-keys varyin number from 1 to 9, respectively, and correspond to the value of thenumerals on the said keys that is to say, if the finger-key be numbered9 the ratchet-teeth F of the ratchet-bar attached to said finger-keywill be nine in numher, and so on. The ratchet-teeth F of the bars ofeach bank of keys are adapted and designed to engage differentratchet-sleeves. In other words, the teeth on the ratchet-bars 1attached to the bank of keys 1, are arranged to engage and rotate thesleeve L The teeth on the ratchet-bars 2 attached to the bank of keys 2,are arranged to engage and rotate the sleeve G and the teeth on theratchet-bars 3 attached to the bank of keys 3, are arranged to engageand rotate the sleeve M hence the said ratchet-teeth are differentlylocated on the different sets of ratchet-bars.

At the lower end of each set of ratchetteeth F is a shoulder or stop G,which, by engaging its respective revoluble ratchetsleeve when theratchet-bar reaches the upper limit of its stroke, will absolutelyprevent further rotation of the said sleeve, and hence prevent thenumbered disk geared to and operated by the said sleeve from moving toofar and registering the wrong number.

At the upper end of each ratchet-bar 1 is a forward-extending arm 1*,and pivoted to the front end thereof is a depending link-arm 1 Each ofsaid link-arms has an offset shoulder H on its front side, near itslower end, adapted to be engaged by the lip of the rocking detent T andon the rear side of each of said link-arms, at a suitable distance fromthe lower end thereof, is a shoulder 1*, which is adapted to engage atooth 011 the sleeve G as will be hereinafter more fully described. Aspring K attached to each arm 1 has its lower end bearing againstthe'rear side of one of the link-arms, the function of the said springsbeing to normally hold the link-arms forward in position to cause theirshoulders I to be thrown out of engagement with the ratchet-sleeve G Atthe upper end of each ratchet-bar 2 is a forward-extending arm 2*, andpivoted to the front end thereof is a dependinglink-arm 2. Each of saidlink-arms has an offset shoulder L on its front side, adapted to beengaged by the lip of the rocking detent D, and on the rear side of eachof said link-arms 2 at a suitable distance from the lower end thereof,is a shoulder M which is adapted to engage with the ratchet-sleeve M Theratchet-bars 3 or those attached to the last bankof keys, are notprovided with link-arms such as hereinbefore described, but at the upperend of each ratchet-bar 1 2, and 3 is a rearward-extending arm N In thefront side of the upper portion of the case is a series of threerectangular openings 1 2 3 which correspond to the fingerkeys in theseveral banks. The said openings are covered with transparent glass.Arranged behind the opening 1, at suitable distances apart and in thesame horizontal plan e, is a series of three rectangular frames 1. Onthe lower side of each frame, at suitable distances apart, is pivoted aseries of three bell-crank levers 1 which have their lower arms weightedat their outer ends, as shown. A series of tablets or indicators 1' areprovided at their lower sides with guide-loops 0 which engage the uppersides of t the frames 1, and thereby secure the tablets or indicatorsthereto and adapt them to be moved laterally thereon. There are three ofthe said tablets on each frame, the said tablets on the various framesbeing arranged in oblique lines, and therefore partly behind each other,to effect the necessary economy of space and enable them to be compactlydisposed in the case and to be presented singly to the opening, and thesaid tablets are connected to the upper arms of the bell-crank levers bymeans of links P The said tablets are numbered from 1 to 9,consecutively, to correspond to the finger-keys of the bank 1 and serveto indicate cents or units. The weighted bell-crank levers normally drawall of the tab lets to one side behind the spacesbetween the openings 1and thereby keep the same out of sight. A similar series of tablets (notshown, as they are concealed by the upper portion of the case in Fig. 1)are arranged behind the openings 2 and guided on frames similar to K,and connected to weighted bell-crank levers 2 by links P The saidtablets 2* are numbered from 10 to 90, and indicate dimes or tens, andcorrespond to the numerals or figures on the second banks of keys 2 Asimilar series of tablets 3" are arranged behind the openings 3 adaptedto slide on frames 3 and connected to weighted bellcrank levers 3 bylinks P. The said tablets 3 are numbered from 1 to 9, and indicatedollars or hundreds of units, and correspond to the numbers or values onthe bank of keys 3 From the foregoing it will be understood that thehighest value or sum that may be indicated by the tablets 1 2 3" whenthe tablet of highest value of each series is presented behind therespective openings, is $9.99, the sum appearing thus: $9 9O ets 9 ets.

Arranged from end to end of the case, one above the other and at asuitable distance below the frames hereinbefore described, are a' pairof horizontal guide-bars R. In openin gs in the said guide-bars arearranged three sets of vertical tumblerrods 1 2 3, which have theirupper ends arranged and adapted to engage the weighted arms of thebell-crank levers 1 2 3 respectively. The numbers of the tumbler-rods,bell-crank levers, tablets or indicators, ratchet-bars, and finger-keysare equal. The tumbler-rods are in the same vertical planes with thearms N of theratchetbars, and thereby when each of said ratchetbars isoperated by itsfinger-key its arm N, as the ratchet-bar rises, strikesthe lower end of its respective tumbler-rod, and thereby causes theappropriate -tablet corresponding to the value of the sale or sum to benoted to appear before one of the openings in the case. Springs S arecoiled on those portions of the tu mbler-rods between their guide-barsIt, and the lower ends of said springs bear on collars T on saidtumbler-rods, and thereby norm ally force the latter down, and hencepermit the weighted bell-crank levers to move the tablets from behindthe openings in the case.

A gong or bell U is mounted in one end of the case, and a pivoted hammerV is adapted to strike and sound the same. The said hammer has avertical arm W against the rear side of which presses a coiled spring XA trip-bar Y is arranged lengthwise in the case and has vertical arms Zat its ends, which are pivoted to the standard-plates and serve tosuspend the trip-bar and adapt it to oscillate. Studs A which projectfrom the stand ard-plates, limit the forward movement of the trip-bar,and springs B which bear against the rear sides of the arms Z keep thelatter normally in engagement with the studs. The

vertical spring-pressed arm of the hammer engages the rear side of thetrip-bar, and the front side of the latter is inclined or beveled toform a cam-face G which is in the paths of the collars T.

\Vhen a finger-key is depressed to record a sale and its ratchet-barforces up one of the tumbler-rods, the collar on the said rod as itrises engages the cam-face of the trip-bar,-

tumbler-rod with such force as to drive the collar on the tumbler-rodupward entirely across the cam-face of the trip-bar and to cause thelatter to operate the hammer, as

before stated. As soon as the collar passes up beyond the trip-bar thesprings of the latter force it back under the collar, thereby retainingthe latter and its tumbler-rod at the upper limit of their stroke, andconsequently the bell-crank lever engaged by the upper end of the saidtumbler-rod will be maintained in such position as to display its tabletbefore the appropriate opening until another sale is made and anotherfinger-key is operated. \Vhen this is done, the instant the nextascending tumbler-rod collar engages the tripbar and the latter is movedrearward the collar on the tumbler-rod, which has since the last salebeen supported in an elevated position, will be released, when itsspring will instantly force it down to its normal position, and itsfellow weighted bell-crank lever will return the fellow tablet to itsnormal position out of sight to make way for the tablet announcing theamount of the most recent sale.

The operation then of the sales-registering mechanism is as follows:Before the initial operation of the machine all of the disks 1 2 3 4 5 6must be turned with their 0 or zero marks opposite the opening P, andthis may be effected by applying the wrench or key I to the squared endH of shaft G and turning said shaft in the direction of the arrows inFig. 18 until the shoulders or offsets O', by engaging with the pins L,range all the O-marks of the disks in line with each other and with theopening P. WVe will assume that the first sale that is made is ofthevalue of five cents. The salesman depresses the key 5 of the bank 1 andby so doing causes the ratchet-bar attached to said key and having fiveratchet-teeth F to ascend, and while so doing engages the ratchetsleeveL and turns the same on its shaft through a space equal to the width offive ratchet-teeth or fivetenths of its circumference. This sleeve beinggeared to the disk 1 by the Wheels 1", 1, U, sleeve 1, and N causes thesaid disk to also rotate through the same proportion of itscircumference, and thereby presents the number 5, indicating cents, tothe IIO appropriate opening P. At the same instant the said ratchet-baroperates the tumbler-rod connected to the tablet in series 1 having thenumber 5 and causes the said tablet to be moved to display through theopening 1' indicating cents, and retained there in the manner beforedescribed, and the hell or gong is rung, as also before described. Thesame initial impulse of the finger-key which operated the ratchet-barand registering mechanism will also cause the bar Z to rise and lift theweight-arms X, and hence cause the right-angled tappet-arms A to drawthe rods R upward and cause said rods to disengage the hooks from thestuds I, when the springs K instantly throw the shield-plate E open, andthedrawer opens, in the manner before described, to receive the cash.The weight-arms instantly, when the salesman removes his finger from thekey, by causing the rodZ to depress the inner end of the finger-key,return the finger-key to its normal position and cause the ratchet-barto descend with it. When another sale of the value, say, of four cents,has been made and the appropriate key operated, the sleeve L will havebeen turned through nine-tenths of its revolution and will have broughtits tappet-pin A to a position adjacent to the upper side of the arm Zof the dog X and the disk 1 will have been turned to bring the number 9or the sum of five and four before the appropriate opening P.

NVe will assume that another sale of the value of one cent is now madeand the appropriate finger-key depressed, which will cause theappropriate ratchet-bar of the series 1 and having only oneratchet-tooth F to engage the ratchet-sleeve L on its ascent and turnthe same through a distance equal to one space or the width of onetooth, and thereby complete the rotation of the said sleeve. As thelatter effects this complete rotation the tappet-pin A being inengagement with the arm Z of dog X as before stated, will depress saidarm and cause the dog to release the arm V of the rocking detent T whenthe spring WV will instantly move the said detent rearward. On thesucceeding descent of the ratchet-bar the said detent will engage thelink-arm 1 attached to said ratchet-bar, and said link-arm will be movedrearward thereby against the resistance of the spring K and the shoulderI of said link-arm will engage one of the teeth of the ratchet-sleeve Ggeared to the tens-disk 2 by the mechanism hereinbefore described, andas the ratchet-bar and link-arm complete their descent the shoulder I ofthe link-arm will rotate the sleeve G2 through a space equal toone-tenth its circumference, and hence cause the tens-disk 2 to turnthrough onetenth of a revolution from 0 to 1 and present the latternumber to the appropriate opening P. The shape of the shoulder I is suchthat as soon as it has moved the sleeve G one space the next succeedingratchet-tooth of the said sleeve will engage the rear side of thelinkarm and push the shoulder 1" thereof out of engagement with the saidsleeve G and hence the latter will be only moved the required distance,and as the link-arm continues to descend after thus disengaged from thesleeve Gr its offset shoulder or cam II" will engage the detent T and inmoving down across the lip thereof will return the said detent to itsinitial position (shown in Fig. 2) and cause its arm V to be againengaged by the dog X which will retain the rocking detent T in itsinitial position until the sleeve L has been moved through anothercomplete revolution.

From the foregoing it will be understood that as often as the sum of thevalues registered by the bank of unit-keys 1 exceeds ten the sleeve Lwill be automatically operated to cause the tens-disk 2 to be moved onespace and present its next highest number to the appropriate opening P.Vhen a sale in tens, or the multiple ten, or tenth part of a dollar, iseifectedsay a sale of the value of thirty cents-the operator depressesthe appropriat 0 key having the number 30 in the bank 2, and therebycauses its ratchet-bar 2 to operate the sleeve G through a space equalto threetenths of its circumference, and consequently the tens-disk 2will be moved a corresponding distance by the gear-wheels which connectit to the sleeve G I have assumed that the said disk 2 has been alreadymoved one space by the previous operations of the link-arms of theratchet-bar attached to the unit-keys of the bank 1. Consequently thethree spaces through which the said disk 2 is now turned by theaforesaid appropriate key and ratchet-bar of the bank 2 will cause thenumber 40, or the sum of three tens plus one ten, to appear on said disk2 through its appropriate opening P.

It is understood from the description hereinbefore given of the tabletsor indicators that the appropriate one will be displayed whenever afinger-key of any bank is operated. The highest number that may beregistered by the disks 1 2 is 99, when the figures 9 of said disks aredisplayed through the openings. Each time that the sleeve G is caused tomake a complete revolution, either by the ratchet-bars attached to thekeys 2 or by the link-arms of the ratchetbars attached to the keys1tl1at is to say, either by registering tens or the sums in tens ofunitsits tappet-pin K will engage the arm I of the dog H and cause thelatter to disengage the arm F of the rocking detent E and consequentlyon the succeeding descent of one of the ratchet-bars 2 the said detentwill engage the offset shoulder M on the link-arm 2", attached to saidratchet-bar, and said link-arm will be moved rearward thereby againstthe resistance of its spring, and the shoulder M of said linkarm willengage one of the teeth of the ratchet-sleeve M geared to the dollars orhundreds disk 3 by the mechanism hereinbefore described, and

move said sleeve M one space, and thereby operate the disk 3 one spaceand cause its next highest number to appear before the appropriateopening P.

When a sale of the value of one or any .number of dollars less than. tenis effected,

the salesman depresses the appropriate finger-key in the bank 3 andcauses the ratchetbar 3 attached to said key, to partly turn theratchet-sleeve M and thereby rotate the disk 3 the required numberofspaces to indicate the sum of the sales in dollars previously made plusthe amount in dollars of the sale just being effected.

Vhen the sum of all the sales registered is more than $9.99, the disk3,indicatin'g dollars, will be turned to such position as to cause itspin 3 to engage one of the pins A of the wheel'Xand move the latter onespace, and hence cause the said wheel, which meshes with the wheel 4, tomove the latter and its disk 4 one space, and thereby cause the figure1, indicating tens of dollars, on said disk to appear before theappropriate opening P, and so on until the said disk 4 has been causedto make a complete revolution. From the foregoing it will be understoodthat the highest amount the disks 1 2 3 4 are capable of registering is$99.99, and that this number will be registeredby a single revolution ofthe disk 4. At each subsequent revolution of said disk 4 its tappet-pin4 will be caused to engage one of the pins B of the wheel Y and move thelatter one space, and hence cause the said wheel, which meshes with thewheel 5, to move the latter and its disk 5 one space, and thereby causethe appropriate number on said disk indicating hundreds of dollars toappear before the appropriate opening P, and so on until the said disk 4has been caused to make a complete revolution.

The highest amount that the disks 1, 2, 3, 4,

and 5 are capable of registering is $999.99.

At each subsequent revolution of the disk 5 its tappet-pin 5 will becaused to engage one of the pins 0 of the Wheel Z and move the latterone space, and hence cause the said wheel, which meshes with the wheel6, to move the latter and its disk 6 one space, and thereby cause theappropriate number on said disk indicating thousands of dollars toappear before the appropriate opening P.

The highest amount that the disks 1, 2, 3, 4, 5, and 6 are capable ofregistering is $9,999.99; but by increasing the number of disks and theoperating wheels and pins the machine may be adapted to register sums upto any amount.

From the foregoing description it will be clear that three sumsexclusively in units, tens, and hundreds may be registeredsimultaneously by depressing the appropriate finger-key of each bank.

A machine constructed with three banks of keys such as shown is capableof regisbers of banks and ratchet-sleeves and ratchetbars, link-arms,and detents the machine may be rendered capable of registering'a sum ofany desired amount. On one of the standardplates is pivoted a detent Dhaving a squared notch atits free end ,which en gages the squared end Hof the shaft G, and thereby holds the said shaft firm and prevents itfrom rotating, excepting when the said detent is disengaged from theshaft and the latter rotated by the wrench or key I to set the disks tothe-zero or naught point, as before stated.

It is of importance to prevent more than one key of each bank from beingoperated at any time, for the reason that the ratchet'bars have varyingnumbers of teeth, and all the ratchet-bars of one set operate the samesleeve, which is geared to an indicating-disk, and therefore if two'keysof a bank were depressed at once only the key operating the ratchethaving the largest number of teeth would be effective in operating theregistering mechanism and the value of the other key would be lost, andhence the efficiency of the machine Would be impaired.

I havedevised means to prevent the operation of more than one key ofeach bank at the same time, and the following is a description thereof:A rectangular open frame is arranged in the case near the rear sidethereof and extends from one standard-plate to the other. The said frameis divided into as many divisions F as there are banks of keys bymeans'of vertical bars The rear ends of the arms X of the finger-keysextend through the said divisions and at the ends of the latter arestops or studs 11. Pivoted to the upper side of each division'of theframe is a series of eight hangers I, the lower ends of which extendinto the spaces between the arms X there being one of said hangersbetween each pair of said arms, and the said lower ends of the hangersare beveled on opposite sides to a downward-extending point. The upperends of the hangers are gradually narrowed, as shown, and the combinedwidth of all the hangers in each division plus the width of one of thekeyarms X is equal to the space between one pair of the stops or studs Hhence when the rear end of one of the finger-key arms X is moved upwardwhen the key is depressed the said arm moves the hangers laterally andthe latter open only a sufficient distance to clear the said arm beforethey come in contact with the stops or studs H and consequently renderit impossible to operate another key of the same bank. On the rear sideof each hanger, at a suitable distance from the lower end thereof, issecured a crosscleat K which cross-cleats serve to thicken the saidhangers and prevent them from overriding each other in the event thattheir pivot-connection should work loose. Arranged across the ease, nearthe rear side thereof, is a lock-plate L which has its ends providedwith pivots N, that engage bearings in the standard-plate. The saidlock-plateis arranged at a slight distance in rear of the frame and hasthe depending flange N and the inclined offset 0 the latter extendingtoward the frame E and the said flange N of the lock-plate has its loweredge in a plane slightly higher than the upper sides of the finger-keyarms when the latter are at rest. The flange N 5 is below the pivots Mand the offset 0 is above the same. A spring P bears against the rearside of the lock plate at a point near its center and normally retainsthe lock-plate in the position shown in Fig. 2, with its flange Ninclined rearward a sufficient distance to clear the rear ends of thefinger-key arms.

The operation of this portion of my i1wention is as follows: hen afinger-key of one or more banks is depressed, the inner ends of the armsthereof rise, and by engaging the inclined offset 0 partly turn thelock-plate on its pivot and cause the flange N to move forward over thearms of the remaining keys, and hence lock them and prevent them frombeing operated until after the pressure on the finger-keys in use hasbeen removed and the said keys have returned to their initial position,when the springs P restore the lock-plate to the position it formerlyoccupied.

It is necessary to provide some means for indicating the number of timesthe registering-disks have been set to zero or naught in order toprevent tampering with the machine for dishonest purposes in the eventof a somewhat prolonged absence of the proprietor, and I have devisedthe following for this purpose:

The shaft G is provided near its squared end II with pins R whichproject therefrom and are four in number, and in line with the squaredfaces of end H and loose on the said shaft is a registeringdisk S whichhas a series of numbers on its periphery from O to 20, or any othersuitable num her, and has a spur-wheel T with a similar number of teeth.An opening U is made in the plate R, to which the numbers on the diskare successively presented. A short shaft V is secured to one of thestandard-plates at a suitable distance above the shaft G, and on saidshort shaft is mounted a revoluble sleeve WV, which has a series oftappets or teeth X adapted to be engaged by the pin R and a pinion Ywith a similar number of teeth, that engage the wheel T There being fourpins R corresponding to the squared end H, each time the shaft G isturned through one-fourth of a revolution by the key or wrench I thetooth X engaged by the pin R will cause the sleeve to turn a sufficientdistance to move the disk S geared thereto, through one space; hence bynoting the number seen through the opening U when the machine is set oradjusted the proprietor when he returns can ascertain at a glancewhether the machine has been set again during his absence.

It is also necessary to provide some means for indicating whether theback of the case is removed during the absence of the proprietor. Toeffect this I employ a disk Y, which is similar to the disk S and has aspur-wheel The numbers on the said disk pass before an opening A in theplate R. A rod B is supported in a horizontal position by guides C andextends from within a suitable distance of the wheel Z to the removablerear side of the case. A coiled spring E is arranged on the rear end ofthe said rod and bears between the rearmost guide C and a transverse pinF. (See Fig. 2.) To the front end of the said rod is pivoted a pawl G,which engages the wheel Z by gravity. When the back of the case isremoved, the spring moves the rod rearward and causes the pawl to slipback on the spurwheel and engage a tooth one space in rear of the toothit formerly engaged, and when the back of the case is again placed inposition it moves the rod forward against the resistance of the spring,and in so doing causes the pawl to move the wheel Z and disk Y onespace, and thereby cause the appropriate number to appear before theopening A.

It is also necessary to provide a register for the lid S to indicate thenumber of times, if at all, thelatter is opened during the absence ofthe proprietor. To effect this I provide a numbered disk II, which isexactly similar to the disks S Y and has a spur-wheel I. The said diskis also loosely mounted on the shaft G, and its numbers appear insuccession before an opening K in the plate R. A vertically-movable rodL is guided in suitable support-s M and has its upper end normallypressed against the lid S by a spring N. To the lower end of the saidrod is pivoted a pawl 0 and a spring I is attached to the rod and bearsagainst the pawl and keeps the latter at all times in engagement withthe wheelI Vhenever the lid S is raised, the spring N moves the rodupward and causes the pawl to slip upon the wheel I a distance of onetooth or space and engage another tooth thereof, and when the lid isclosed it presses down on said rod and causes its pawl to move the wheelI and disk II a distance of one space, and thereby cause the appropriatenumber to appear before the opening K".

The plate R (shown in Fig. 2 and for the sake of clearuess omitted fromFigs. 1 and 3) covers the front sides of the various registeringmechanisms, renders them inaccessible, and hence prevents them frombeing tampered with when the lid is opened. The various shafts,tumbler-sleeves, ratchet-sleeves, gears, and ratchet-bars render theregistering mechanisms inaccessible from the rear when the back of thecase is removed.
